I checked all my fuses, and everything looks good. I just don’t have power at the climate change. No air is coming from vent.

Hi,

Does the blower motor fan operate? In other words, do you hear it running but there is no airflow? Also, when you checked the fuse, did you confirm there is power to and from it?

I attached the wiring schematic below. I highlighted the fuse that powers the HVAC display module. I need you to confirm there is power to and from that fuse. Here is a link that you may find helpful:

If the fuse checks good and there is power to and from it, then I need you to check for power at the HVAC display module. The power is provided via a black wire with a yellow tracer. It should have power with the key in the on position.

Also, pic 3 shows the specific fuse to check in the under-dash fuse box. It's fuse 30.

Let me know what you find or if you have other questions. Also, let me know if you hear the fan run.

Take care,

Joe

See pics below. Note: I had to cut the schematic in half to make it readable for you. I did overlap them so you can follow from one to the next.
